Former first daughter Barbara Bush married Craig Louis Coyne in a private ceremony in Maine on Sunday.

The couple exchanged vows at Walker's Point in Kennebunkport, Maine, in front of family, according to a statement from the office of her father, President George W. Bush.

"Barbara is named for a unique and strong woman — and rightly so, because she is unique and strong. @laurawbush and I are so proud of our compassionate, daring, fierce, kind, intelligent, loving daughter. And we’re thrilled to welcome Craig Coyne to our family," the former president wrote on Instagram.

The bride's twin sister, Jenna, wrote in an emotional post on Instagram, "Happy tears, heart exploding as I watched this beautiful girl get married in the place that means love and family. I’m so proud to be this beauties sister." She added in another post, "My heart exploded last night as I watched my dearest sissy get married in Maine. It was just like her: private (only family!) and full of love (and yes lots of tears!)."
